Description

451007 A7 B7 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. 5. Description of the Invention (1) The present invention relates to a rather thin, heterogeneous knitted fabric including metal fibers and other fibers. Among them, more specifically, plus The yarn composition of the area on one surface is different from that on the other surface. If other fibers can also withstand severe temperatures, knitted fabrics can be used in very cold or very hot environments. Heterogeneous knitted fabrics conventionally comprising metal fiber yarns are known from the applicant's patent WO 9 4/0 1 3 7 3. The knitting pattern can thereby behave differently on its surface and / or the entire fabric thickness. Patent WO 9 4/0 1 3 7 2 also discloses the use of such heterogeneous fibers as a barrier cloth when molding plate glass at high temperatures. There is also an increasing demand for processes and other applications involving very thin heterogeneous knitted fabrics that incorporate metal fibers with a relatively high air permeability and some degree of insulation. The weight of these fibers is preferably kept to a minimum, although it must contain a portion of the gold ray fiber. The heterogeneous knitted fabric comprising metal fibers of the present invention is intended to meet this need, which is achieved by providing a flat knitted structure in which a yarn with a high metal fiber content is close to one surface and a yarn with a low metal content is close to another surface . The "high metal fiber content" here is at least 30% by volume metal fibers, preferably above 40% by volume, and even yarns including 100% by volume metal fibers. "Low metal fiber content" here means less than 12% by volume, preferably less than 7% by volume of metal fibers. The aforementioned low-content yarn may even be composed of 100% other fibers. These may be carbon, glass, basalt, ceramic or synthetic fibers. Knitted fabrics typically weigh less than 2000 grams per square meter, and preferably 1500 grams per square meter.

They become so-called twin yarns and can be flat woven into wefts on a circular knitting machine or on a flat loom. If necessary, mechanical separation is possible, mainly depending on the thickness of the yarn, 5 to 30 gauges in circular knitting, and 5 to 20 gauges in plain knitting. The so-called mechanical separation refers to "each inch of needle bed" The number of stitches "is also commonly referred to as the" gauge ". Yarns with high metal fibers and yarns with low gold fibers are therefore drawn closer to the same knitting needle for knitting at the same time, both of which are sufficient to form a plain The tension of the fabric (single woven layer), the yarn system is constantly innovated. Yarns with a low gold content are usually smoother than yarns with a high metal content. This is helpful for flat knitting operations.> Yarns with a high metal fiber content are preferably with a diameter 4 micron to 50 micron metal fiber, For example, stainless steel fibers, staple fiber yarns. The yarn on the reverse side of the cloth can be 100% glass, basalt or carbon or synthetic filaments with a diameter of less than 40 microns. Suitable synthetic filaments include polyaramide or polyurethane. Filament filaments (Kevlar®, du Pont Nemours brand, Twaron®, AKZO / ENKA brand). Spinning, regardless of whether it is a twisted yarn containing one or more fibers, is equally suitable. "During the plain weaving process, a yarn (High metal fiber content) can be used as another (low or no metal fiber) to produce a fabric with different areas per square meter in weight, density (breathability), stretchability, or electrical conductivity. The fabric may also contain, for example, fine interlining yarns for reinforcing fibers, such as the applicant's Belgian patent application 9 7/0 0 6 1 4.

This gives a knitted fabric containing a relatively thin heterogeneous knitted fabric on a part of its surface. The cloth is therefore heterogeneous over its entire thickness range and its surface. EXAMPLES Through the examples, a specific example of the knitted fabric of the present invention and its use for isolating the fabric during compression-molded plate-like peeling will be described in further detail below. However, the present invention is not limited to this or a similar polymer embodiment, "The fabric is made on a Stoll CMS 440 plain weaving machine with a pitch of 12 stitches to make a single-sided knitted structure without the need to cross stiffen the yarn. After removing all the brightener from the cloth, the thickness of the cloth was about 1 mm. The cloth weighs 62.5 stitches per square centimeter and weighs 980 g / m2. The air permeability of this fabric is 4 1 6 4 (liters / hour / 10 cm2), so it is suitable as the inner lining of the male section of the compression model. The glass fiber surface of the fabric is in contact with the model, so the appearance of the metal fiber is in the mold. Contact with the glass plate is formed during the manufacturing process. In this insulation fabric, the twisted (fibril) high metal fiber content yarn is composed of 100% diameter 12 micron, 133 tex Bekinox type AISI 3 16L fiber. Low metal fiber content yarns are composed of 100% 13 6 tx glass filament yarns. If the heterogeneous knitted fabric of the present invention forms a combustion thin film of a gas burner, a roving is used. The separation operation on the knitting machine can be set to, for example, 5.
